But that’s entirely the point… there are millions of ideas and ideas are cheap and usually impractical to implement anyway. The only people that will come up with practical solutions how to produce insulin are the workers in a future existing insulin factory that find themselves in a society transitioning to more equitable and anarchist inspired ideals. And they will figure it out somehow as there is no technical barrier and they clearly have a product in high demand for which the people around them also easily understand why it is needed.

One of the big reason why Marxist socialists and the more anarchist leaning ones (usually the ones with practical experience from labour unions) split up more than hundred years ago, was because the Marxists continued to come up with all these harebrained theories and proposals for the future and then used these ideas to justify doing bad things in the here and now. Anarchists always clearly said that this is a sure way to end up in a dystopia, as the end can never justify the means and I think the history of the USSR and similar states clearly proved them right on that point.

The anarchist idea is to ensure the means and methods you employ to reach your imagined more equitable future society are a mirror of what you want to eventually achieve. And this clearly works as there are right now worker owned and controlled cooperatives with complex supply chains, building complex technical equipment all based on anarchist principles with annual turnovers of tens of billions of dollars. Such a cooperative could also easily produce insulin or other pharmaceuticals and would clearly have the needed resources to solve eventual supply chain issues.
